IMPROVENIENT IN RAILROAD-CAR HEATIRS.

The chenle referred to in these Letters Patent and making part of the'lamq.

To all whom it may concern Bc itknown that we, GEORGE S. KooNTz, of Washington, in the countyof Washington, and District of Columbia, and EDWARD Po'rrs and McLnoD D. Lnwrs, of Baltimore, in the county of Baltimore, and State of' Maryland, have invented a new and useful Improvement in Railroad-Car Heaters, for extinguishing fire, in cases of coiiision, overtming, orpzzrtizti overturning of the cars, or other like accidents; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon. l

The` nature of our invention consists in a fire-extinguisher, so arranged that the furnace shall be in ready communication with the water-chamber, which is of sheet-iron, or other suitable material, constructed to contain water.

Through the top of this vessel is a rod, F, constructed at its lower end with a valve, G, and at its upper end with a chain, H, attached to a ball, I,-rest ing within a ring, J, which is supported by braces, a a.

In cases of collision, or overturning, or partial overturning of cars, or like accidents, the ball I, preponderating the chain, rods, and valves in the chamberpipe, will roll from the ring J, and raise the valves G and M, so that the water in the chamber E willbe thereupon discharged into a pipe, of suitable dimensions, K, extending from the valve G into the furnace A, thus extinguishing the tire therein, and obviating the possibility of damage or loss of life by fire.

At the base of the pipe K, which is perforated, for the escape of heated air, is a second valve, M, for the further exclusion of heat from the chamber E, -avoiding thereby the generating of steam in said chamber,

which, when formed within the furnace A, in cases of collision, overturning, or partial overturning, or other like accidents, escapes through the furnace-pipe N.

A jacket, C, made of sheet-iron, or other suitable material, forming a chamber, is made to surround the furnace A, for the purpose of heating air, to be conveyed to the interior otA the car, equalizng the heat thcrem) through a ue,"D, atta ed to the bottom of the car, running one-fourth its length, or thereabouts, from both ends; and,besides, in addition to the draught, Q, in front, is a pipe, O, connecting with and extending from the rear of the air-chamber P, through the car-door, for the conveyance of cold air.

' The valve M is connected to the valve G by a rod, R, so that when the valve G is displaced, it opens the valve M, and allows the water to enter the furnace A.

Having thu's fully described my invent-ion,

What we claim as new, and desire to secure by Letters Patent, isv l. The water-tank' E,when.n1ade substantiallyas shown anddescribed, and placed vertically over the stove, in combination with the ball I, chain H, and valve G, all as and for the purpose specified.

2. The combination of valve G, rod R, and valve M, all as and for the purpose specified.

3. The combination of the ball I, chain H, and valve G, all substantially as shown aud described, with the ring J, supported on braces a a, substantially as and for the purpose specified.
